My issue was that qantas refunded to anz, anz didnt see the refund, I went back to qantas, they say they refund me, back and forth a few time, until a "better" anz agent found trace of the money, but I had to hang up at that time for an important meeting, then no other anz agent found the money, until it get escalated, then they realise they got the money, but since I don t have an anz account, send it back to qantas after 30 days, then I had to write a stat dec for qantas to send it to another account etc... Really not fun.
Again, I had a few easy refund process, but all it take is that one terrible experience to understand it's not worth taking risks. ANZ throwing 200AUD as a sorry, is clear evidence of their incompetence in handling that refund. And during this whole time, I was convinced it was Qantas the problem, because of their terrible refund reputation at that time.
